What should I do if my EVAP Monitor says no?
⇒ If any of the I/M System Status indicators display NO, refer to the Inspection/Maintenance (I/M) System DTC Table for the indicator which did not display YES. The I/M System DTC Table identifies the DTCs associated with each I/M System Status Indicator. Follow the Conditions for Running the DTC in order to set the associated status indicator.
How does the control module test the EVAP system?
The control module uses several tests to determine if the EVAP system is leaking. This tests for large leaks and blockages in the evaporative emission (EVAP) system.
How to reset the EVAP system monitor drive cycle?
Connect the Scan Tool to the data link connector (DLC). Use the Scan Tool to clear any stored DTC’s and to reset the Onboard Diagnostic Monitors. Bring up the Readiness Code for the EVAP System Monitor. 2. Start the engine (cold); IAT PID from 40-100ºF (this step requires a key “off” period of at least 8 hours). 3.
What happens if the EVAP test fails again?
If the decay rate is more than a calibrated value, the control module will rerun the test. If the test fails again, a DTC P0442 will set. If the evaporative emission (EVAP) vent system is restricted, fuel vapors will not be properly purged from the EVAP canister.
How to check the status of the EVAP system monitor?
Then decelerate back to 0 mph without touching the brake pedal or the clutch pedal on models with manual transmission. Allow the engine to run at idle speed for 20 seconds. Bring the vehicle to a stop in a safe place, but do not turn off the ignition key. 4. Check the status of the Readiness code for the EVAP System Monitor.
Why is the EVAP monitor on my OBDII not working?
Upon hooking up my OBDII scanner I see that the EVAP monitor is the only one left still under pending not complete status. So seems like the dealer either reset the codes (which there was none) or disconnected the battery just to replace the door handles. Well I didnt know so thats why the emissions is failing.
What should I do if my EVAP is not working?
⇒ If the EVAP Service bay test is NOT available, it may take up to 6 drive cycles, with up to 17 hours between drive cycles, for the EVAP I/M System Status indicator to transition to YES. ⇒ If the O2S Heater System Status indicator displays NO, ensure that the ignition has been turned OFF for at least 10 hours.
Why is my EVAP failing to get I / m readiness?
I just want to get my 06 9-7x 5.3L to pass the e-test, which is just a check for no codes and I/M readiness. All systems have to run through the required cycles and have passed. My evap is failing to complete. I’m not getting any DTC codes, no MIL, just keep getting “Incomplete” for the evap system in Torque.
